This paper deals with social infrastructure planning problems to determine the location of the facilities of social infrastructure network and the layout. Each user must be assigned to the closest facility to be economically viable. The objective is how to make the accessibility to facilities maximum (i.e., to minimize the distance which the users traveled to reach the facilities). In this pape...

Facility location-network design (FLND) problem, which determines the location of facilities and also communication links between the demand and facility nodes, is arisen from the combination of the facility location and network design problems. This paper deals with fuzzy capacitated facility location-network design model which aims to select the facilities and candidate links in a way that yi...

OBJECTIVES To compare availability, cost, affordability and sources of anti-diabetic drugs between private and public health facilities in Dar es Salaam, Tanzania. DESIGN Cross sectional descriptive study. SETTING Diabetic clinics in private and public health facilities in Dar es Salaam, Tanzania. SUBJECTS Eighty patients randomly selected and 45 health facility personnel staff working in...

regarding the fiscal constraints and management difficulties of public hospitals, several countries have usedpublic private partnership model to improve their health facilities. public private partnership enables using public resources and private investment and expertise in a combined structure. moheb hospital is the first iranian hospital managed according to public private-partnership. the p...

a facility location is said to be competitive when other facilities are present in the market and new facilities have to compete with these existing facilities for a market share. in other words, in a competitive facility location problem we do not see monopoly that exists in classic location models. in such a situation, existing facilities react to locate new facilities by adjusting their attr...

The spatial distribution of urban service facilities is largely constrained by the road network. In this study, network point pattern analysis and correlation analysis were used to analyze the relationship between road network and healthcare facility distribution. The weighted network kernel density estimation method proposed in this study identifies significant differences between the outside ...

The optimal locating of facilities has large effects on economic benefits, providing satisfactory service and levels of customer satisfaction. One of the new topics discussed in location problems is hub location and hub facilities are subject to unpredictable disruptions. This paper proposes a nonlinear integer model for reliable single allocation hub location problem that considers backup hub,...

In this paper we propose five heuristic procedures for the solution of the multiple competitive facilities location problem. A franchise of several facilities is to be located in a trade area where competing facilities already exist. The objective is to maximize the market share captured by the franchise as a whole. We perform extensive computational tests and conclude that a two-step heuristic...
